Although the company welcomed the government's idea of going for all-electric vehicles by 2030, BMW said lack of infrastructure and consumer's concerns over getting stranded with pure electric vehicles when charge runs out will be major challenges to overcome.
Under the GST rates, tax incidence on hybrid vehicles will go up to 43 per cent from the current level of effective tax rate of 30.3 per cent.
In a plug-in hybrid electric vehicle, apart from a conventional petrol or diesel engine, there is a large battery that is recharged from an outlet by plugging in thus enabling it to drive extended distances using just electricity.
On the other hand, in normal hybrid vehicle, battery is charged from energy generated from running conventional engine and the range offered on electric drive mode is shorter.

"We would have liked plug-in hybrids to be included as part of the electric vehicles," he added.
"If we want to achieve results earlier, then the approach should be plug-in hybrids leading to pure electrical vehicles. That will make transition much easier but with current policies it does not allow us to do that," he added.
He asked the government to look "at plug-in hybrid as equal to electric vehicles for the transition phase" to accelerate movement towards green mobility.
BMW already sells both pure electric and plug-in hybrid vehicles across the world.
"One, infrastructure needs to be set up to go purely electric and that will take time. It cannot happen immediately," he said.
The second challenge is the concern among consumers of getting stranded in the middle of the road when the battery charge runs out, he added.
"So the transition to electric mobility from a customer viewpoint would be a bigger hurdle," Pawah said.
The government is working on a scheme to provide electric cars on zero down payment for which people can pay out of their savings on expensive fossil fuels, for becoming 100 per cent electric vehicle nation by 2030.
Auto industry has already said that the increased tax incidence on hybrids is against the government's long-term goal of promoting green vehicles in the country.
